__Visual and Bacterial Factors__
The observed wildlife at the Long Island Creek Site 6B study area consisted of waterfowl, amphibians, fish, and insects. There were a fair amount small fish and some medium sized fish. There was one fallen tree upstream near the footbridge, but was not heavily obstructing the waterflow or fish movement. There some algae floating in a side pool on this section of the creek. Despite the relatively large amount of trees, about 70% of the water was totally exposed to direct sunlight.

__Tree Risk Assessment __
Group six conducted an urban ecology study of site 6 on Long Island Creek within the East Palisades Chattahoochee River National Recreation Area. Site 6 consists of two separate locations, site A and Site B. At site B, we conducted a risk assessment on 10 different trees within our area of study using the USDA Community Tree Evaluation Form. These trees are numbered 11-20 because of the trees in site A. Trees 11-15 are located on the right bank and trees 16-20 are located on the left bank as you look up stream. The follow chart shows the trees in trees and the risks that we calculated:

__Results__
This chart shows all trees 10 trees we selected for this risk assessment along with the defect codes. This risk assessment notes that site 6B has a higher number of the Yellow Poplar Trees (LITU) at this location with 3 out of the 10 are this species. The trees at this site have a lower level of risk because of their location within the protected area of the NPS. Trees 12 a Boxelder(ACNE) and 17 a Carolina Silverbell (CACA) we determined to be at highest risk and may need to be monitored because of the recreational activities that occur at the park. Overall the trees at site 6A are in relatively good shape and should be left alone to grow naturally because of their location in the protected forest.
